моя служба кода:
describe('Component: Auth', () => {
let component: AuthService;
let fixture: ComponentFixture<AuthService>;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [AuthService]
})
fixture = TestBed.createComponent(AuthService);
component = fixture.componentInstance;
});
});
Вы можете спросить меня, в чем проблема?
Ответы 2
Используйте его, как показано ниже:
Сервисы должны быть в массиве providers.
describe('Component: Auth', () => {
let component: AuthService;
let fixture: ComponentFixture<AuthService>;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [],
providers: [AuthService] // **Like this.**
})
fixture = TestBed.createComponent(AuthService);
component = fixture.componentInstance;
});
});
Вы должны создать экземпляр сервиса: let service = new AuthService();, нет необходимости вызывать createComponent и тому подобное.
